Enhanced Photocatalytic Activity of BiVO4 for Water Oxidation by Mo Doping

Abstract

Photocatalytic activity of BiVO4 for the water oxidation was found extensively improved by Mo doping. The highest activity of Mo doped BiVO4 for O2 evolution appeared when the photocatalysts was doped by 0.2 at % Mo. The XRD patterens showed that the crystal structure of the photocatalyst was changed by Mo doping. The color and UV-Vis absorption spectra of the photocatalysts were also changed before and after the catalysts were doped by Mo.
